Description

Technical Field

[0001] The utility model relates to the technical field of bridge supports, in particular to a bridge support. Background Art

[0002] A bridge is a building built for roads to cross natural or artificial obstacles. It is erected on rivers, lakes, and seas to allow vehicles and pedestrians to pass smoothly. A bridge is generally composed of a superstructure, a substructure, and ancillary structures. The superstructure mainly refers to the span structure and the support system, the substructure includes abutments, piers, and foundations, and the ancillary structures refer to the bridgehead slab, conical slope protection, revetment, diversion projects, etc. Bridges are divided into four basic systems according to the structural system: beam bridges, arch bridges, rigid frame bridges, and cable-bearing (suspension bridges, cable-stayed bridges). In the construction of bridges, bridge bearings are needed. Bridge bearings are connected to the superstructure of the bridge. It is an important structural component of the lower structure and is located between the bridge and the pad stone. It can reliably transmit the load and deformation (displacement and rotation) borne by the upper structure of the bridge to the lower structure of the bridge. It is an important force transmission device of the bridge. There are two types of fixed bearings and movable bearings. The commonly used bearing types in bridge engineering include oil felt or flat bearings, plate rubber bearings, spherical bearings, steel bearings and special bearings, etc. Then the traditional bridge bearing only adds a rubber buffer pad at its buffering part, resulting in poor effect on the bridge bearing, resulting in reduced safety of bridge use, thereby reducing the practicability of the bridge bearing. Therefore, a bridge bearing is proposed.

[0003] After searching, the patent announcement number CN215104624U discloses a bridge bearing, including an upper slide plate, a slide seat and a self-tensioning fastener, the upper slide plate is fixedly installed on the bottom wall of the bridge bottom plate, the slide seat is slidably arranged on the main truss through the self-tensioning fastener, the bottom wall of the upper slide plate is provided with a groove 1, the groove 1 is a rectangular structure, the top of the slide seat is embedded in the groove 1, the slide seat includes an inverted truncated cone support plate and a lower slide plate, the inverted truncated cone support plate is arranged on the upper wall of the sliding plate, the upper side wall of the inverted truncated cone support plate is tangent to the long side of the groove 1, the inverted truncated cone support plate is provided on the upper wall of the sliding plate, the upper side wall of the inverted truncated cone support plate is tangent to the long side of the groove 1, and the inverted truncated cone support plate is provided on the upper wall of the sliding plate. Ball bearings are evenly arranged on the top of the support plate. However, in the prior art document, only a rubber buffer pad is added to the buffer part of the bridge bearing, resulting in poor effect on the bridge bearing, reducing the safety of bridge use, thereby reducing the practicability of the bridge bearing. In addition, in the prior art document, the rubber buffer part of the bridge bearing is exposed to the air or simply shielded, which makes the buffer part susceptible to erosion and damage by dust or insects and birds, thereby reducing the service life of the bridge bearing and increasing the maintenance cost of the bridge bearing.
